Acoustic absorptive panel

Abstract

An acoustic absorptive panel comprises a continuous face layer, a first acoustic absorptive layer located on a rear surface of the face layer, wherein the absorptive layer includes at least one channel having a channel opening terminating at or near an outer edge of the continuous face layer.

1 . An acoustic absorptive panel comprising:
 a continuous face layer,   a first acoustic absorptive layer located on a rear surface of the face layer,   wherein the absorptive layer includes at least one channel having a channel opening terminating at or near an outer edge of the continuous face layer.   
     
     
         2 . The acoustic absorptive panel of  claim 1 , further comprising a second acoustic absorptive layer located between the continuous face layer and the first acoustic absorptive layer. 
     
     
         3 . The acoustic absorptive panel of  claim 2 , wherein the second acoustic absorptive layer is continuous. 
     
     
         4 . The acoustic absorptive panel of  claim 1 , wherein the continuous face layer defines a hard surface formed from one of:
 laminate;   whiteboard;   timber;   MDF;   plywood;   plasterboard;   compressed fibre cement;   metal;   glass; or wallcovering, ceramic,   polymer.   
     
     
         5 . The acoustic absorptive panel of  claim 1 , wherein the continuous face layer defines a flexible material formed from one of: laminate or a wallcovering. 
     
     
         6 . The acoustic absorptive panel of  claim 1 , wherein the first acoustic dampening layer is formed from PET acoustic backing. 
     
     
         7 . The acoustic absorptive panel of  claim 1 , wherein the channel has a body portion which is larger in cross-sectional area than the channel opening. 
     
     
         8 . The acoustic absorptive panel of  claim 1 , wherein the channel body is elongated having an open proximal end opening onto the channel opening and an enclosed distal end. 
     
     
         9 . The acoustic absorptive panel of  claim 8  wherein the open proximal end is rounded. 
     
     
         10 . The acoustic absorptive panel of  claim 9 , wherein the enclosed distal end is rounded. 
     
     
         11 . The acoustic absorptive panel of  claim 1 , comprising a plurality of said channels. 
     
     
         12 . The acoustic absorptive panel of  claim 11 , wherein each of the channels extends generally parallel with each other. 
     
     
         13 . The acoustic absorptive panel of  claim 1 , wherein the panel defines the writing surface of a wall mounted or free-standing whiteboard. 
     
     
         14 . A method of forming an acoustic absorptive panel, the method including the steps of:
 forming at least one channel in a first acoustic absorptive layer, the channel having at least one channel opening terminating at or near an outer edge of the first acoustic absorptive layer, and   locating the first acoustic absorptive layer on a rear surface of a continuous face layer.   
     
     
         15 . The method of  claim 14 , further including the step of placing a second acoustic absorptive layer between the continuous face layer and the first acoustic absorptive layer.
